Masaail relating to intimacy

Fantasizing about other women

Q: I am married to my cousin (mother's side) 6 years ago.This was a pure arranged marriage and neither of us had any likeness apart from the fact that we were cousins before marriage. We both try to make salaah on time and we take care of each other as well.

My question is that what does Islam say if a husband has no physical attraction towards his wife despite so much efforts to feel attracted to her but still no feelings. During intercourse he only gets aroused sexually by imaging other women. Otherwise its not possible for him to get arouse sexually.

Kindly guide me what to do as this is killing me from inside. I don't know how long I can live like this. Besides this we have no arguments and no fights. She takes good care of me and I do the same, but it's only this one thing and it's happening for more than 5 years. What should I do? 

Intimacy between spouses

Q:

1. Is is necessary to change the bedsheet every time after having sex? As some fluids may come on it.

2. Is is possible for wife to masturbate his husband's penis?

3. What is the best treatment for premature ejaculation and erectile dysfunction? Any ayurvedic drinks or any thing according to Islam?

4. Is it permissible for both of us to take shower together ?

Anal sex with wife

Q: I want to know what is the kafara of doing anal sex with your wife when she is in her monthly periods . The husband claims that it was by mistake but the wife said that it was on purpose and this thing happened the second time and the first time both agreed that it was by mistake. I know there is a way in Islam to batch up with your wife if a person does toubah and promises not to do this thing again but what will be the kafarah?

Husband drinking wife's breast milk

Q:

1. Is it permissible for my husband to drink/swallow my milk intentionally and unintentionally. I am breastfeeding his son. Whilst making love to me he squeezes my breasts and sucks my nipples very hard and there is milk all round his mouth and I know he is also taking it inside.

2. Am I responsible to make food for my father in law when my husband calls me to bed to fulfil his needs and satisfy him?
